as far as I saw, vote aren't really correlated with quality in a match, i.e. alot of time I scored 7-8 goals and the opposite gk got a 7 :-)
I just think that if your players aren't involved in the match their vote is generally low. So I suppose that you play only on the wings... and I'm not surprised at all that your mc get lower vote. Who cares?
btw: fantastic right wing!
